+   Here are brief descriptions of the filename formats supported by this class:
+
+   wxPATH_UNIX: standard Unix format, used under Darwin as well, absolute file
+                names have the form:
+                /dir1/dir2/.../dirN/filename, "." and ".." stand for the
+                current and parent directory respectively, "~" is parsed as the
+                user HOME and "~username" as the HOME of that user
+
+   wxPATH_DOS:  DOS/Windows format, absolute file names have the form:
+                drive:\dir1\dir2\...\dirN\filename.ext where drive is a single
+                letter. "." and ".." as for Unix but no "~".
+
+                There are also UNC names of the form \\share\fullpath
+
+   wxPATH_MAC:  Mac OS 8/9 and Mac OS X under CodeWarrior 7 format, absolute file
+                names have the form
+                    volume:dir1:...:dirN:filename
+                and the relative file names are either
+                    :dir1:...:dirN:filename
+                or just
+                    filename
+                (although :filename works as well).
+                Since the volume is just part of the file path, it is not
+                treated like a separate entity as it is done under DOS and
+                VMS, it is just treated as another dir.
+
+   wxPATH_VMS:  VMS native format, absolute file names have the form
+                    <device>:[dir1.dir2.dir3]file.txt
+                or
+                    <device>:[000000.dir1.dir2.dir3]file.txt
+
+                the <device> is the physical device (i.e. disk). 000000 is the
+                root directory on the device which can be omitted.
+
+                Note that VMS uses different separators unlike Unix:
+                 : always after the device. If the path does not contain : than
+                   the default (the device of the current directory) is assumed.
+                 [ start of directory specyfication
+                 . separator between directory and subdirectory
+                 ] between directory and file
